Hello again gentleman, so I bought a 72 with a seized engine. I've read it's fairly common from car siting for 10+ years. I've read about the mystery oil and ATF, coke and even read about towing the car and popping the clutch to free up engine. I just received the car last Friday and What I'm trying first is mystery oil soak. It's been 4 days and nothing. I'm thinking about pouring some HOT ATF and trying that. Has anyone had success on freeing up a seized engine? Also, I need ideas for trying to turn the crank pulley instead of just the bolt, I'm worried it will break. Maybe even taking starter out and try turning the flywheel with a pry bar. What do you guys think? Greatly appreciate your time guys
